This is a huge issue. A family member spent two weeks in the hospital last year, and one of the hardest parts of that experience was how difficult it was to sleep there. The light, the noise, the demented patient shouting in the next room, the constant interruptions and questionnaires from nurses and doctors: you just couldn't sleep more than 90 minutes if you were lucky. We called them "the bleeping machines", in the double sense. I would turn them off sometimes, because the stats they were monitoring were not life or death for us. Hospitals are a place where there is no night. The nurses working on the graveyard shift under the bright fluorescents cover a third of the day, and for them, it's just another workday, but it runs from 11pm to 7am. And they treat patients as though it is daytime. Don't get me wrong, the nurses were great, but the structure and incentives don't favor sleep. There is so much that could be done to help patients get better faster, by giving them a more restful environment. But the incentive is to monitor them until you can get them out of the bed, to save everybody money.
